Question

In a triangle if the ratio of angle A & angle B is A:B=5:3 and angle C=100° then A and B=​

Answer 1

Step-by-step explanation:

The angles of the triangle are in the ratio: 5:3:7

Let the angles be 5x,3x,7x

By Angle sum property,

5x+3x+7x=180

15x=180

x=12

Thus, angles are, 60

,36

∘

,84

∘

Since, all the angles are less than 90

∘

, it is an acute angled triangle.
